North Carolina's Department of Environmental Quality (NCDEQ) has recently released updated guidance for the Lead Service Line Inventory (LSLI). This guidance provides water systems with four core elements to help them classify service line materials using statistical methods and predictive modeling.

The first element of the guidance is for water systems with no lead, providing them with clear instructions on how to classify their service lines. The second element is for water systems with known or suspected lead, offering guidance on how to classify unknown service lines. The third element outlines the number of physical verifications required, ensuring that water systems inspect a certain percentage of unknown service lines.

Additionally, the guidance includes approval and reporting requirements for all water systems. This ensures that water systems comply with the guidelines set forth by NCDEQ.
